Preset management for Pd Vanilla
by Alexandre Torres Porres 13 Nov '23

13 Nov '23

Never really needed fancy preset management other than storing messages in a basic vanilla way. But I've seen people mention how Pd lacks a nice preset system. Not that I know what a fancy one actually needs since I never felt the demand. So I'm here to ask what people use in Pd Vanilla, be it a pure vanilla solution or an external. And also to ask what people miss. This is what I came up with as a pure vanilla abstraction, it's based on [text] and [savestate]. Here's the thing: https://drive.google.com/file/d/1A0ISEJo5F1E578WHM1doo1n2CJAthonU/view?usp=… In short, the preset abstraction takes messages and stores them. You can have many of these on your patch and use them to recall presets for any parameters. It takes any kind of messages. I'm making use of built-in sends and receives in the number boxes to make the patch cleaner. Just think that you can have separate control of each parameter having its own preset or group all of them together globally, or a group here and another there, whatever... Once you save the patch, the presets you saved get stored in the patch. As for my current idea for my ELSE library, I'm using an object similar to grab to take messages from [receive] objects. It's a development over this original vanilla abstraction. My first draft is this, I hope that sharing the screenshot give you a nice idea.

soundtouch~ for Pd Vanilla
by Alexandre Torres Porres 31 Oct '23

31 Oct '23

Hi folks, I'm on a vibe of uploading missing libraries and objects for Pd Vanilla on deken. On the list I have FFTease, Lyonpotpourri, CICM-Tools and more stuff that I'm looking into, just so you know... Now, I see there's an old soundtouch~ external here: http://www.katjaas.nl/pitchshift/soundtouch~.html - it's "version 0.9" by Katja Vetter. It was developed with SoundTouch version 1.6 and Pure Data version 0.42. I tested on Pd 0.51-4 32 bits on mac and it works fine. There are binaries for download on the link above, but not for 64 bits. I wonder if anyone wants to help me build these with pd-lib-builder and all. Now, the ceammc librarym (and Pd-ceammc distribution) has a soundtouch~ external too. It's the same name, but not the same external, this one is marked as "version 0.1". So we do already have "a" soundtouch~ for vanilla, but I wanted to also get katja's external up there. So I just uploaded the download from that page here https://github.com/porres/pd-soundtouch - It's just the download as it is and we need to change to hopefully use pd-lib-builder, which would make things easier. I did try that and it didn't work. So, anyone onboard with this? cheers

Multiple audio outputs on a single-board computer ?
by Pierre Massat 14 Jul '21

14 Jul '21

Dear all, I haven't posted anything on this list in years. I'm trying to build a system to play several sound files in a loop, each around 2 minutes in length, all at the same time. By "several" I mean 10 to 15 different files. While I'd have no problem making a Pd patch to achieve this, I have no idea what hardware I could use. I have a limited budget, and I was planning on running Pd on a Raspberry Pi (or similar single-board computer). Is there any cheap way of outputing than many channels from a single (a couple of) RPi ? Thanks in advance, Pierre.

changing pd~ samplerate programmatically
by Jean-Yves Gratius 28 Mar '21

28 Mar '21

Hello, I have to synchronize the samplerate inside a camomille VST plugin that uses a pd~ subprocess, with the samplerate used by the host. I'm aware that we can specify samplerate of subprocess pd~ on creation with the flag -sr <samplerate> as [pd~] argument. But is there a way to dynamically change this ? (other than by sending a message such as [;pd audio-dialog 2 0 0 0 2 0 0 0 2 0 0 0 2 0 0 0 96000 30 -1 64( to the subprocess, where only the samplerate value --here 96000-- is relevant ?) thanks

Image from shader back to Gem
by Csaba Láng 26 Mar '21

26 Mar '21

Dear List, I am using a camera with a fisheye lens for motion detection. The distortion had to be corrected with a shader (method from Matlab) but now I need to rotate the image and crop it with pix_crop plus analyze the frames with pix_movement. How can I get back the image to Gem? In my patch gemframebuffer send the image to the shader but not a clue how I could ise the pix_ objects again. [image: Screenshot 2021-02-14 at 17.27.12.png] This is the corrected image from the camera after shader [image: Grid corrected.jpeg] Let me know please where I miss something. Best, Popesz

Netreceive + osc issue
by Rick Snow 24 Mar '21

24 Mar '21

Hi all, I wonder if anyone can help me out with this issue. I’m receiving an OSC message using [netreceive -u -b 7002] from another piece of software on the same computer. Netreceive is producing an error in the console reading: “recv (bin): a message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram into was smaller than the datagram itself. (10040)” The OSC message does not print from the outlet on netreceive. I’m running this on a PC on 0.51.4. Thanks for all advice! Cheers, Rick

moocow string2any
by marco 24 Mar '21

24 Mar '21

Hello! I am trying to migrate a Pduino Patch from pd-extended to Pd-Vanilla and the only object that is missing is "moocow/string2any". (A weird thing is that on Linux I was able to find moocow in the external search from pd-vanilla, but on Windows I am not.) However, I wanted to ask if there is a possibiliy to substitude the function of "string2any" with a more common PD Operation or something I can still find in the externals. Big thanks! Marco
